1. An optical scanner which comprises:
a fixed planar support;
a beam, provided with a first face and with a second face, held secured by one of its ends, called a fixed end, to the planar support and perpendicular to a main face of said support;
an actuator arranged to impart either a bending or a torsion on a movable portion of the beam extending from a free end of said beam and opposite to the fixed end;
an optical source adapted to emit a main optical beam with a wavelength λ;
a plurality of waveguides disposed on or in the beam and intended to split the main optical beam into a plurality of secondary optical beams;
an optical phased array which comprises a plurality of optical phase-shifters each coupled to a waveguide, disposed on or in an emission section of the movable portion and which extends from the free end, the emission section having a transparency adapted to enable light extraction from the first face and from the second face.
